Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan Effective Microorganisms-4 (EM-4) pada proses anaerobik limbah organik terhadap peningkatan konsentrasi ammonium (NH4) serta mengevaluasi penambahan ion Magnesium (Mg) dan Pospat (PO4) terhadap penurunan konsentrasi ion NH4 dalam proses pembentukan struvite. Meskipun telah ada penelitian sebelumnya mengenai pengaruh penambahan ion Mg dan PO4 dalam pembentukan struvite, namun penelitian yang secara khusus memperhatikan pengaruh penambahan EM-4 masih terbatas. Penelitian ini menggunakan limbah organik, kotoran sapi, dan EM-4 dalam proses anaerobik untuk menghasilkan peningkatan konsentrasi NH4, yang kemudian digunakan untuk pembentukan struvite dengan penambahan ion Mg dan PO4, serta dianalisis menggunakan SEM dan EDX. Hasil penelitian menunjukkan bahwa penambahan EM-4 sebesar 60 ml dalam proses anaerobik limbah organik menghasilkan peningkatan konsentrasi NH4 yang signifikan dari 97 mg/L hingga 350 mg/L. Pada Proses pembentukan struvite kristal menunjukkan bahwa penambahan ion Mg dan ion PO4 memiliki efek yang signifikan dalam penurunan konsentrasi NH4 hingga mencapai 53,6 mg/L dan meningkatkan kemurnian struvite yang dihasilkan yaitu 65%. Analisis Scanning Electron Microscope (SEM) dan Energy Dispersive X-Ray Analysis EDX memberikan gambaran tentang hasil pembentukan struvite dan keberadaan pengotor dalam struvite. Penelitian ini memberikan kontribusi dalam pemahaman tentang pengaruh penambahan EM-4, ion Mg, dan ion PO4 dalam pembentukan struvite melalui proses anaerobik limbah organik, serta menekankan pentingnya penelitian lebih lanjut untuk pemahaman yang lebih baik dalam pengolahan limbah organik secara efektif dan berkelanjutan.Kata kunci: Anaerobik, limbah organik, Effective Microorganisms-4 (EM4), struvite

Abstract

This study aims to analyze and optimize the effect of Mg anode and sodium dichromate sacrificial protection on the corrosion rate of carbon steel in Musi River water media. The research involved carbon steel pipes (½ inch, 1 cm length) with an ID of 18.20 mm and OD of 18.80 mm. Four variables were tested: A (no corrosion prevention), B (Na2Cr2O7), C (Mg anode), and D (Na2Cr2O7 with Mg anode), each immersed in 150 ml of Musi River water for periods of 20, 30, 40, 50, and 60 days. Results showed the highest pH drop in variation A, where the initial pH of 6.87 decreased to 4.13 after 60 days. Variation A also showed the greatest increase in Fe concentration, rising from 1.47 mg/L to 4.89 mg/L, and turbidity from 80.8 NTU to 88.3 NTU after 60 days. Corrosion rate analysis indicated that carbon steel without corrosion prevention had the highest corrosion rate, reaching 0.0000025746 mpy after 60 days. In comparison, carbon steel with Na2Cr2O7 and Mg anode protection exhibited significantly lower corrosion rates. These findings highlight carbon steel pipes without corrosion protection experience higher degradation in Musi River water, while sodium dichromate and Mg anode treatments effectively reduce corrosion.

Abstract

When temperature increases, energy efficiency tends to decrease. This is because the materials in solar panels, especially photovoltaic cells, have characteristics that make them less efficient at converting solar energy into electrical energy when temperatures rise. By using the random forest research method and Rstudio software to help analyze it can be concluded that the temperature variation that has the most influence on power efficiency is light intensity with a contribution of 19%, then air temperature with 18%, humidity with 17.5%, wind speed with 14%. 5% and finally panel temperature with a contribution of 13%. This contribution is the contribution to the power produced by the effect of temperature on the power produced. at 10.13 the highest power was obtained, where the power produced was 164.48 Watts. With a light intensity of 431.44 cd (candela), air temperature of 41.9°C, humidity of 49.4%, wind speed of 0.2 m/s, and panel temperature of 35 °C

Abstract

The recovery of nutrients from contaminated water and wastewater can effectively mitigate both the nutrient burden on water resources and the associated environmental issues affecting aquatic ecosystems. This approach presents a valuable solution towards achieving environmental and societal sustainability. Consequently, struvite crystallization technology has emerged as a promising method for nutrient recovery, as the resulting precipitate can be recycled as a natural fertilizer. This review aims to elucidate the characteristics of struvite and provide insight into the fundamental process of crystallization. Furthermore, it comprehensively discusses the various variables that influence struvite crystallization, with a special focus on its application in urine-contaminated water using electrochemical methods. The review also highlights the advantageous on environmental and economic aspects. In addition, the limitations of struvite crystallization technology are examined, and future research prospects are explored, particularly in the context of electrochemical techniques which offer innovative solutions for controlled nutrient extraction. Ultimately, this work serves as a foundational resource for the future utilization of struvite crystallization technology in nutrient recovery, in response to the escalating environmental challenges and depletion of natural resources.Keywords: Struvite formation, electrochemical process, magnesium anode, struvite crystallization, natural fertilizer

Abstract

Penggunaan plastik yang terus meningkat berbanding lurus dengan jumlah limbah plastik yang dihasilkan. Salah satu alternatif yang dilakukan adalah dengan me-recycle limbah plastik dengan proses pelelehan biji plastik atau plastik yang telah dicacah.  Pada mesin peleleh plastik skala laboratorium, proses pelelehan yang terjadi akan dipengaruhi oleh berbagai faktor. Metode yang digunakan pada penelitian ini adalah dengan menggunakan pendekatan Faktorial.  Tujuan dari percobaan faktorial adalah untuk melihat interaksi antara faktor yang di uji. Adakalanya kedua faktor saling sinergi terhadap respon (positif). Namun adakalanya juga keberadaan suatu faktor justru menghambat kinerja faktor lain (negatif). Pada penelitian ini faktor pertama  adalah  bahan  yaitu jenis plastik yang digunakan (PP, PET, dan HDPE).  Faktor kedua adalah temperatur yaitu 300? C, 350? C, 400? C dan faktor ke tiga adalah waktu  yang terdiri dari 25, 30 dan 35 menit. Berdasarkan hasil penelitian yang dilakukan secara manual dan dibandingkan juga dengan hasil dari perhitungan minitab, didapatkan bahwa faktor utama bahan, temperatur dan waktu berpengaruh nyata tetapi interaksi antara 3 faktor tersebut berpengaruh tidak nyata.

Abstract

The Human Development Index (HDI) is an important indicator for assessing the success of regional development, particularly in the aspects of health, education, and economy. However, as an aggregate indicator, HDI cannot yet specifically represent the unique development needs of each region. Therefore, a decision support system (DSS) approach is needed to analyze HDI components more deeply and objectively. This study aims to compare two multicriteria decision-making methods-Simple Additive Weighting (SAW) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS)-in ranking the HDI of regencies/cities in Central Java Province in 2024. The HDI data was obtained from the Central Statistics Agency (BPS) 2024, covering the three main dimensions of HDI. The analysis results show differences in ranking orders between the two methods, indicating that the choice of analytical method can influence development interpretations and priorities. This study makes a significant contribution by providing a data-driven approach to support more targeted regional development policies.

Abstract

Restitution (Compensation) is a development or can be said to be a shift from criminal fines, this shift does not eliminate the application of criminal fines. The fundamental difference between criminal fines and restitution is that in criminal fines, compensation for losses incurred is given to the state, while in restitution, compensation is given to the victim or their family. In several material laws that regulate restitution, basically only regulate the definition of restitution and the mechanism for submitting applications but do not regulate the definition of third parties who are part of the restitution itself. Therefore, the researcher conducted research through normative methods supplemented by interviews with several law enforcement officials, it is hoped that it will obtain a comprehensive picture of third parties in restitution. The reconstruction carried out by the researcher is found in the Law on Witness and Victim Protection, namely Law Number 31 of 2014 concerning Amendments to Law Number 13 of 2006 concerning Witness and Victim Protection, where the researcher added a formulation regarding third parties who are not criminal perpetrators. The additional article that is a reconstruction of the research is in Article 1 number 12, which reads "A third party is a party other than a criminal perpetrator who has a legal relationship with the perpetrator of a criminal act in the same crime." With the reconstruction of the formulation of the definition of a third party used in several material laws, it is clear and obvious who the legal subjects are who can be qualified to be held accountable for paying restitution.

Abstract

Penelitian ini mengeksplorasi potensi pemanfaatan limbah bonggol jagung menjadi briket arang dengan menganalisis pengaruh temperatur karbonisasi dan rasio perekat lem kayu terhadap sifat fisik dan kimia briket. Mengatasi kesenjangan dalam pemanfaatan limbah biomassa, penelitian ini mengoptimalkan temperatur karbonisasi (200°C hingga 400°C) dan rasio perekat (1:1, 1,5:1, dan 2:1) untuk meningkatkan efisiensi bahan bakar dan stabilitas struktur. Hasil penelitian menunjukkan bahwa temperatur karbonisasi 400°C dengan rasio perekat 1:1 menghasilkan briket dengan kadar air terendah (3,9%) dan kadar abu terendah (2,9%), serta nilai kalor tertinggi (6172 cal/g). Temuan ini menunjukkan potensi briket bonggol jagung sebagai sumber energi alternatif yang berkelanjutan dan berkualitas tinggi. Penelitian selanjutnya disarankan untuk mengeksplorasi jenis perekat tambahan dan rentang suhu yang lebih luas guna menyempurnakan proses produksi dan memaksimalkan kinerja bahan bakar.
